A significant reduction in the properties of recycled aggregate concrete (RAC) made of 100% RCA was seen when compared to natural aggregate concrete (NAC), while the properties of RAC made of a blend of 75% NA and 25% RCA showed no significant change in concrete properties.
This paper investigates experimentally and analytically the shear performance of RC beams made of recycled coarse aggregate (RCA).
The inferior qualities of recycled concrete coarse aggregates (RCA) relative to natural coarse aggregates (NCA) can unfavorably affect the properties of concrete made using RCA.
Finally, someone from RCA just wanted to apologize to me on behalf of RCA.
Laboratory tests are performed to investigate the effects of a new method of mixture proportioning on the creep and shrinkage characteristics of concrete made with recycled concrete aggregate (RCA).
TUFT--Leonard W., 83, retired Executive Vice President of RCA, died Friday, November 11, of heart failure.
The current laboratory investigation analyses the fatigue performance of HMA made with recycled concrete aggregates (RCA).
The title and idea for this essay came to me after my local congregation, a congregation of the Reformed Church in America (RCA), through much prayer, made a "covenant of sharing and caring" with another local congregation of the Presbyterian Church (U.S.A).
Results of a comprehensive investigation about the durability of structural-grade concrete made with recycled concrete aggregate (RCA) are presented.
Durability performance of Self-Compacting Concrete (SCC) made with Recycled Concrete Aggregates (RCA) as partial or full replacement of Natural Coarse Aggregates (NCA) and with selected mineral admixtures as partial replacement of Portland Cement (PC) is reported.
